OVEN FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 436,788, datedSeptember 23, 1890.

Application filed January 3, 1888. Serial No. 259,540. (to model.)

To all whom it may concern.-

' Be it known that I, JosIAH J EWETT, a citizen of the United States,residing in the city of Buffalo, in the county of Erie and State of NewYork, have invented certain new and useful Improvements in Ovens forStoves and Ranges, of which the following is a specification, referencebeing had to theaccompanying drawings.

This invention relates to such stoves and ranges as have an ovenfurnished with a laterally-swinging door and with a segmental slide,shelf, or grate arranged to be slid part way out and in on theoven-bottom in an arc of a circle or a curved course.

The general objects of this invention are to construct the oven-doorwith an opening at its lower part, and the oven-slide with a handleextending through said opening and outside of the oven when the doorisclosed: First, so that the door can be freely opened without drawing outthe slide, and that when the door is closed the slide can beconveniently drawn out byits handle and the door thereby simultaneouslyopened; second, so that when the door is opened by drawing out the slideby its handle the drawn-out side of the slide will be supported by theopened door; third, so that when the door is opened by drawing out theslide by its handle the slide will be so automatically locked to orengaged with the door that the two cannot be carelessly disengaged whilethe door remains far open, and, fourth, so that when the door is openedby drawing out the slide the opening of the door and the drawing out ofthe slide shall be antomatically stopped when the slide is drawn out toa predetermined extent. These objects are attained by the meansillustrated in the accompanying drawings, in which- Figure 1 is aperspective view of a portion of a cooking stove or range having itsoven furnished with one form of myinvention, and showing the oven-slidedrawn out and its drawn-out side supported by the opened ovendoor. Fig.2 is a plan and partial section of a similar oven door and slide withthe door closed and a handle on the slide and extending therefromthrough and beyond an aperture, slot, or opening in the door, and suitedto permit the door to be opened freely without drawing out the slide,and so that the door will be opened by drawing out the slide by itshandle. extending outside of the door. Fig. 3 is a plan and partialsection of the same,- showing the slide pivoted or mounted to move in anarc eccentric to that of the swing movement of the door, and the slidedrawn out and the door opened as by drawing out the slide by its handleextending outside of the door, and the drawn-out side of the slidesupported by hearing on a lower part of the door, and the slide solocked to or engaged with the door that the slide cannot he accidentallyor otherwise readily disengaged from the door while the slide remainsfar drawn out, and the openinglnovement of the door and the drawing-outmovement of the slide automatically stopped by the meeting of stops onthe slide and door. Fig. 4: represents a vertical section of parts ofthe same, on a larger scale, at about the linez z in Figs. 2 and 6. Fig.5 is a similar section of parts of the same at the line 'yy in Figs. 3and 7. Fig. 6 is an elevation showing the outside of apart of the lowerportions of the oven-door, and the handle of the slide when the door isclosed, as in Figs. 2 and 4:. Fig. 7 shows in elevation a part of theouter side of the lower portion of the door and the handle of the slidewhen the door is opened, as shown in Figs. 1, 3, and 5. Fig. 8 shows theunder side of the handle on the oven-slide, and Fig. 9 shows the slotthrough the lower portion of the oven-door represented in Figs. 2 and 8.Figs. 10, 11, 12, 13, and 14. illustrate a modification of the parts bywhich the outer side of the slide is supported by and engaged with thedoor when the door is opened by drawing out the slide, Fig. 10 being asection at the line was in Fig. 11, which is a sectional plan ofadjacent parts of the oven-bottom, door, and slide, with its handle whenthe door is closed. Fig. 12 is a plan of the same parts of the door andslide with its handle when the door is opened by drawing out the slide.Fig. 13 is a front elevation of a part of the slide with its handle, andFig. 14 is an elevation of the inner side of the part of the door withwhich the slide is engaged in Fig. 12.

A is the oven-bottom; B, the oven-door, hinged at c to swing to and frolaterally, and

furnished on its outer side with its usual handle, lug, or knob, and Dthe quadrantshaped or segmental slide, which can be slid out and in onthe oven-bottom in a curved course or are of acircle eccentric to thecourse of the swinging movement of the door.

E is a handle, which is on and carried by the slide, and which when thedoor is closed extends in any suitable shape outside of the door througha slot, notch, or opening f in the lower part of the door, so as topermit the door to be freely opened and closed without moving the slideout or in, and so as to allow a person to take hold of the handle whereit extends outside of the closed door, and thereby draw out the slideand simultaneously open the door. The opening f has somewhat greatersize and horizontal extent than the handle E on the slide, and is shownin Figs. 1, 6, 7, and 9 in the form of a slot, and in Fig. 14. in theform of a recess in the lower edge of the door, which recess may extendas an opening of any suitable size and shape along the door. The shank cof the handle'E has much less horizontal extent than the opening f, soas to permit a considerable sliding movement of the oven-slide or itshandle to and fro along the door while the door is being opened andclosed simultaneously with or by the drawing out and pushing in of theovenslide.

In Figs. 2 and 3 the segmental slide D is shown as pivoted at a-point gaway from or eccentric to the hinge c of the door, so that in drawingout the slide by its handle extending outside of the door, the outerside of the slide is compelled to slide or move along the door, asillustrated by Figs. 2 and 3, be-

cause the centers of the movements of the door and slide are thusseparated or eccentric to each other. l/Vhenever the segmental slide Dis not pivoted in the oven but is entirely loose and free to be movedtherein in varying directions, upon then drawing out the slide andsimultaneously opening the door by the handle E, extending through theopening f and outside of the door, the outer side of the slide willgenerally have a considerable movement inward along the door in thusdrawing out the slide, because of the retarding action of the weight andinertia of the slide, with or without a load of baking thereon; .or insuch case the slide may have the same movement along the door impartedbythe hand of the person who draws out the slide by its handle, andthereby simultaneously opens the door. On the oven-slide is a bearing71, and a corresponding bearing t' is on the door and lower than thebearing h. The bearings h and 2' are so constructed and arranged and areof such extent that when the slide is drawn out by its handle extendingoutside of the door and the door is thereby opened, the part It willthen bear upon and be supported by the bearing z, about as indicated byFigs. 1, 3, 5, 7, and 12, so that thereby the oven door will support thedrawnthe lower side of the slot or opening f serves as the bearing t onthe door.

In the modification illustrated by Figs. 10,

ll, 12, 13, and 14:, the part It on the slide is away from the handle Eand its shank, and the bearing 71 is on the inner side of the door, asmight be the case in Figs. 2, 3, at, and 5, and as indicated in thosefigures by dotted lines at h 01.

In order to automatically lock the slide to the door so that the twowill not be accidentally disengaged when the door is opened by drawingout the slide, the slide is made with a locking catch or bearing 70,which is outside of and opposite to an opening Z in the door when thedoor is closed, as illustrated in Figs. 4, 6, and 11, so as to thenfreely permit the door to be opened and closed without moving the slide,and which part 70 travels in one di-, rection along the outside of abearing m on the door as the door is opened by drawing out the slide, asindicated by Figs. 5, 7, and 12, and travels in the reverse direction toopposite the opening Z in closing the door and simultaneously shoving inthe slide. This automatic locking of the slide to the door by themovement of the part hot the slide along the part m of the door as theslide is drawn out by its handle and the door thereby opened, I

occurs whether the slide'is loose in the oven or is pivoted therein, asat g; but in the latter case the pivoted slide cannot be even willfullydisengaged from the door while the slide remains far drawn out.

To automatically stop the simultaneous drawing out of the slide andopening of the door when the slide is pivoted at g and is drawn out to acertain extent, I arrange on the slide or its handle and on thedoor-stops, so as to thereby prevent drawing the slide too far out ofthe oven. This is illustrated by Fig. 3, wherein the stop n on the shankof the handle of the slide is shown as arrested by the stop 0 at theinner end of the opening through the door.

In carrying out this invention the handle E, which is on and carried bythe quadrantshaped or segmental slide D is commonly in tegral with orfirmly secured to the slide, as

shown by full lines in the drawings; but the handle can be secured tothe slide so as to have a limited movement thereon, as indicated bybroken lines in Fig. 2, by being pivoted to the slide at w, so as tohave a move ment to and fro in the directions of the arrows 1) and u,and limited in the direction of the arrow to by a stop at t on theslide.

Whenever the segmental slide D is pivoted to the door or concentricallywith its hinge, as by having fast on the slide a lug extending to andaround the axis of the door-hinge door can be looked to and unlockedfrom the I slide by the parts is and m by moving the handle E to and froby hand along the door when the handle is pivoted to the slide, asindicated in Fig. 2 at w, and above specified.

I claim as my invention- 1. The combination, with the oven furnishedwith the door hinged to turn laterally and having the opening in itslower part, of the quadrant-shaped slide on the ovenebottom, the handlepermanently secured to the slide and smaller than said opening andextending freely through it and outside of the door when closed andpermitting the doorto be freely opened and closed without moving saidhandle or slide, and the fixed bearing on the door to support the slidewhen it is drawn out and the door simultaneously opened by means of saidhandle extending through said opening and outside of the door,substantially as set forth.

2. The combination, with the oven furnished with the door hinged to turnlaterally and having the opening in its lower part, of

I the quadrant-shaped slide on the ovexbbottom and having the handlepermanently secured to the slide and smaller than said opening andextending freely through it and outside of the door when closed,theslide-supporting bearing z' and locking-bearing m on the door, and thecorrelative bearings h and k on the slide, substantially as described.

3. The combination, with an oven furnished with a door hinged to turnlaterally and having an opening at its lower part, of a segmental slideon the oven-bottom and pivoted at g eccentrically to the hinge c of thedoor, and having a handle extending through said opening and outside ofthe door when closed, substantially as described.

4. The combination, with an oven furnished with a door hinged to turnlaterally and having an opening at its lower part, of a segmental slideon the oven-bottom and pivoted eccentrically in relation to the hinge ofthe door, and having a handle smaller than said opening and extendingthrough it and outside of the door when closed, and stopsn and 0, one onthe slide or its handle and the other on the door, as described.

5. The combination,with an oven furnished with a door hinged to turnlaterally and havin g an opening f at its lower part, of thequadrant-shaped slide on the oven-bottom and pivoted eccentrically inrespect to the hinge of the door, and having the handle E smaller thansaid opening and extending through it and outside of the door whenclosed, and the slide-supporting and looking bearings c'and m on thedoor and h and k on the slide or its handle, substantially as set forth.

6. The combinatiomwith the oven furnished with the laterally-swingingdoor B,having the opening f at its lower part, of the segmental slide'Don the oven-bottom and pivoted eccentrically in relation to the hinge ofthe door, and having the handle E smaller than said opening andextending through it and outside 75 of the door when closed, and theslide-supporting and locking bearings and stops '6, m, and 0 on the doorand h, 70, and n on the slide or its handle, substantially as set forth.

In testimony whereof I hereunto set my hand, in the presence of twosubscribing witnesses, this 28th day of December, 1887.
